Description

At work, we are working with Java, so we have many modules. I've set up description template for each repository. So, I tried to set up a git repository for all our templates, and then I tried to set up this template repository as a submodule of the Java module repositories, but it didn't work as I expected.

Maybe it is a bad idea. I don't know if it's great to do something like that.

Proposal

Make description template available in a Gitlab repository using a submodule called .gitlab.

Links / references

I saw these non-related issues which could be great too for the use case. I'm just wondering what's better 🤔 :

gitlab-ce#13729 gitlab-ce#30957 gitlab-ce#22310

Use cases

For company working with many similar projects like micro-services oriented architecture with one service per repository, it could be great to version description template in another repository and add it as a submodule of these repositories

I hope I am clear enough. By the way, Gitlab is great ! 😃
